Any pointers on how to figure out what its capabilities are? (other than just trusting the synaptics driver to figure it out, which I've already tried but don't like the result). I've googled for some of those values, but didn't turn up anything meaningful (to me). -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------

Since The Main Thing I would like to have that I cannot get working are two-finger horiz/vert scrolling, this seems to say that the device does not recognize (and never will) that feature. Even though the Mate touchpad settings show they are enabled, as does synclient. My thought on this is: :-( :-( :-( :-( :-( :-( Sigh. I guess that since the laptop was free, I shouldn't complain.
